    摘要: The present invention relates to a thermoelectric material containing CoSb.sub.3 compound for converting heat to electricity, and provides a p-type thermoelectric material of CoSb.sub.3 having a high power factor by achieving high Seebeck coefficient consistently with high electric conductivity in a material of CoSb.sub.3 system without causing increase in heat conductivity. By sintering Co.sub.0.07 Pt.sub.0.03 Sb.sub.3 alloy powder using the spark plasma sintering technique, the material is densified, while growth of grains is restricted, so that a higher electric conductivity is achieved with a heat conductivity maintained in a low level, and the figure of merit as a heat-transfer material is improved. Also, by providing such heat insulating layer as an oxide intermediately in a grain boundary of a compound of CoSb.sub.3 in a sintered body, the heat conductivity is reduced. Further, the Seebeck coefficient is increased by adding a rare earth metal to the thermoelectric material of CoSb.sub.3, and allowing it to be precipitated in grain boundaries of the sintered body.

    摘要: A piezoelectric pressure sensor is provided with a sensor housing including an inner sensor housing, accommodating an piezoelectric element, and an outer sensor housing threaded to a test article. The inner sensor housing is attached to the outer sensor housing in such a manner that a prestress applied to the piezoelectric element does not change due to an axial strain in the outer sensor housing. The axial strain is produced when the outer sensor housing is mounted to a test article.
